A design method of universal wireless sensor networks node

It is a new design method of embedded system to design hardware and software based on component during the development process of embedded system. The method can improve the reusability and portability of embedded system significantly. For the extensive application of wireless sensor networks, the design method of a universal wireless sensor networks node, with which hardware can be cut and software can be configured, is proposed in this study. According to the design method of component-based, the hierarchical design model of the software is improved. The hardware component design and software component design is discussed and the development details of bottom software component is given. It is proved that the node can be applied quickly, that improves the efficiency of wireless sensor networks' application development, because of the hardware can easily be extended and the software with clearly interface. © 2013 Asian Network for Scientific Information.
